HARRY W. BENI-IARD, OF SAN FRANCISCO, CALIFORNIA.

Lacasse.

Application filed January 21 1918.

To all vrc/wm may concern:

le it known that I, HARRY W. DENHARD, a citizen of the United States,and a resident of the city and county of San Francisco, State ofCalifornia., have invented a certain new and useful Bookmark, of whichthe following is a specification.

The invention relates to book marks.

An object of the invention is to provide a book mark which isparticularly applir-'able for use in connection with the readingl ofChristian Science lessons.

it. further object of the invention is to provide a series of bookmarks, formed to notify the reader when he should stop his rea ding.

A fui-ther object of the invention is to provide a book mark on whichthe passages 'to be read on a given page may be marked.

The invention possesses other advantageous features, some of which, withthe foregoing, will be set forth at length in the following descriptionwhere Ishall outline in full that form of the invention which I haveselected for illustration in the drawings accompanying and formingpartcf the present specification. In said 'drawings l have shown onespecific form of my invention, but it is to be understood that I do notlimit myself to such form, since the invention, as expressed in theclaims, may be einbodied in a plurality of forms.

Referring to said drawings:

Figure l shows the mark of in place on the page of a book.

Fig. :2 is a view of the book mar t.

rI`lie book mark of my invention consists preferably of a strip oftransparent flexible material, such as celluloid, which is cut intothree strips f l-1l, by the two longitudinal cuts M()V which terminatein small holes or enlargements T, which occur adjacent the ends of themark. The three strips are, therefore, integral, being joined togetherat their ends. The longitudinal cuts are of substantially the sainelength as the height o f the page of the book in which the mark is to beused, so that the page may be inserted through the two cuts, causing twoof the strips 2-/l to lie on one side of the page and the strip 3 to lieon the other side of the page. The enlargements 7 at the ends of thecuts form openings for the edge of the page, preventing the mark frombinding as it is placed or removed and preventing it from tearing theedge of the page.

my invention Specification of Letters Patent.

Patented Mar. 23, 1920.

Serial. No. 212,914.

At each end the mark is provided with integral. tabs 8-9 which projectfrom the top and bottom of the book. A plurality of marks aie requiredto form a set and the marks forming a set are consecutively numbered orotherwise marked so that they may y be readily located. Each mark isprovided on the tabs with a number or character 12,

there being a different number or character for each niark ofthe set. Ina set of thirty marks, the tabs are `numbered successively from l to 30.rIhe numbers on the opposite ends of each mark are the same, but

means are provided for differentiating the 7o two ends. This may beaccomplished by making the numbers on the two tabs of different color orby surrounding each number with a field of different color. In the marksshown in the drawings, the numbers at one end of the marks aresurrounded by a black field 13 and the numbers at the other end of themarks are surrounded by a red iield 14:.

The book mark is preferably made of celluloid having a ground surface,which may be readily marked on with a pencil.

In Christian Science work, weekly lessons are assigned and these lessonscomprise a plurality of passages from the Bible and a Bible and then apassage from Science cmd Healtwhich refers to the passage in the Bible.A. lesson comprises approximately thirty passages in `each book and thebooks are read alternately, making it necessary to locate sixty passagesin the study of the weekly lesson. The book marks of my invention areused to mark these passages so that the student may turn from one bookto the other, with the least loss of time. Frecuentl several se arated)assaoes in the Y P l e Bible must be read consecutively and thenseveral separated passages in Science cmd [IeeZZ'i are readconsecutively and the mark of my invention indicates to the reader whenhe has finished the group of passages in one book, `so that he may thenturn to the other book.

The book mark of my invention is slipped over the page sidewise, withthe two strips 2 4 on that side of the page on which the lio passage tobe read occurs, or where it begins. Pencil marks are made on one or bothof the vstrips to indicate the beginning and ending to the page, thepencil marks cannot become displaced. On a two-column page, if thepassage begins and ends in the rst column, tivo pencil marks are made onstrip 2; ijt' it begins in the first column and ends in second column, a'pencil mark is made on each of. strips 2 and 4L at the beginning andending of thepassage; if it begins in the second column and ends on theother side of the page, a pencil mark is made on strip 4 to indicate thebeginning and a mark is made on strip 3 to indicate the endoi' thepassage. The marks are inserted in the book With 'the tabs arranged sothat the numerals therethe tabs of one color project at one end of thebook. When several passages are to be read consecutively in one bookbefore turning to the other book, the mark indicating the last passageof the several to be read is reversed so that a tab of different coloris presented at the top of the book. For instance `if three separatedpassages in one book are to be read consecutively the book marks bearingthe characters l and 2 will begarranged so that the red field tabsare'exposed at the top of the book and the book mark bearing thecharacter 3 will be arranged so that the black field is exposed at thetop of the book. This indicates to the student that after reading thepassage marked by the mark-3 he is to refer to the other book.k
